topotecan
Summary
Topotecan is used to treat certain types of cancer, including ovarian cancer and small cell lung cancer. It helps slow or stop the growth of cancer cells by interfering with their DNA replication process, which is the way cells make copies of their genetic material.
Topotecan works by inhibiting an enzyme called topoisomerase I, which is essential for DNA replication in cells. By blocking this enzyme, Topotecan prevents cancer cells from dividing and growing, helping to slow or stop the spread of cancer.
The usual starting dose of Topotecan for adults is 1.5 mg/m², given as an intravenous infusion over 30 minutes daily for five days, repeated every 21 days. This cycle may vary based on your specific condition and doctor's advice.
Common side effects of Topotecan include nausea, vomiting, and low blood cell counts, which can lead to fatigue and increased infection risk. These effects can vary in frequency and severity, and it's important to discuss any concerns with your doctor.
Topotecan can cause bone marrow suppression, which reduces blood cell production and increases infection risk. It's contraindicated in people with severe bone marrow suppression or severe kidney impairment. Always inform your doctor about your medical history to ensure Topotecan is safe for you.
